CHARLES THIBODEAU, OF SOMERVILLE, MASSACHUSETTS, ASSIGNOR TO P. DUFF & SONS, A FIRM, OF PITTSBURG, PENNSYLVANIA.

CAN DY-PULLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 779,141, dated January 3, 1905.

Application filed April 18 1904. Serial No. 203,544.

To all whmn it may concern:

Be it known that 1, CHARLES THIBODEAU, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Candy-Pulling Machines, of which the following is a specification.

Figure 1 in side elevation showsa machine constructed in accordance with my invention. Fig. 2 represents a left-hand elevation. Figs. 3 to 11, both inclusive, are diagrammatic views showing the successive relative positions in relation to each other occupied by the oscillating hook and the rotary hooks.

1 represents a suitable base carrying a vertical standard 2.

3. represents a bearing in the middle and near the lower part of the standard 2. In this bearing is arranged a shaft 4, adapted to be driven in any desired way, (not shown,)

either by means of a pulley or the continuation of said shaft or otherwise, as preferred.

5 represents a sprocketgear fast on the right-hand end of the shaft 4. 6 represents a disk fast on the left-hand end of said shaft.

7 represents a bearing formed at the upper end of the standard 2 over the bearing 3.

8 represents a shaft arranged in the bearing 7.

9 represents a sprocket-wheel fast on the right-hand end of the shaft 8.

10 represents a sprocket-gear fast on the left-hand end of the shaft 8.

11 represents an arm extending up from a hub 22, loosely mountedon the shaft 8 at the left-hand end of the machine and carrying at its upper end a bearing 12.

13 represents a shaft arranged in the bearing 12. 14 represents a sprocket-wheel fast on the left-hand end of said shaft.

15 represents a sprocket-chain connecting the sprocket-wheels 10 and 14.

16 represents a sprocket-chain connecting the sprocket-wheels 5 and 9.

stationary candy-hook 19, said hook extending from the left-hand side of the arm.

pivoted to the free. end of the crank 23, its

opposite end being pivoted to the stud on the disk 6.

represents a double crank mounted upon the inner end of the shaft 13, each arm of said crank being of equal length and carrying at its free end the candy-hook 26 and 26, the hook 19 being substantially in the plane of the arc of movement of the shaft 13.

Power being applied to the machine the rotation of the shaft 4 causes the rotation of the shaft 8, and thereby the rotation of the shaft 13 and of the candy-hooks 26 and 26, about said shaft as an axis. Further, the rotation of the shaft 4, by means of the crank 23 and pitman 24, oscillates the hub 22 and the shaft 8, thereby vibrating the shaft 13 in an arc whose center is the shaft 8. The candyhooks 26 are thus given a movement of rotation about their axis 13 and also a vibratory movement in an arc the center of which is the shaft 8, the latter being in the same vertical plane as the stationary hook 19, so that the extent of the vibration of the hooks 26 and 26 in the form here shown is the same on each side of the hook 19. The speed of the hooks 26 and 26 is so adjusted in relation to the speed of the vibration of the arm 11 that they alternate in position each time they pass the stationary hook 19.

Assuming the parts to be in the position shown in Fig. 3, the candy 40 is placed on the hook 26. In starting the machine the axis of the crank 25 approaches the book 19. The former, meanwhile, rotating upon its axis carries the hooks 26 26 to the position shown in Fig. 4. A further movement of the machine brings the parts to the position shown in Fig. 5, with the hook 19 in contact, or nearly so, with the candy above the hook 26 and below the hook 26". A further movement of the parts carries the axis of the crank past the hook 19 to the position, for instance, as shown in Fig. 6,,the candy having been subjected to a pulling action due to the travel of the parts from the position shown in Fig. 5 to that shown in Fig. 6. A further movement or operation of the machine brings the parts to the position shown in Fig. 7, where the crank 25 has nearly reached the limit of its travel in one direction and the hook 26 is about to pass the hook 19. Fig. 9 shows the position of the parts, with the hook 26 past the hook 19 and in position for the crank 25 to begin its reverse vibrating motion. Fig. 9, compared with Fig. 3, shows substantially on'e revolution of the pin 13 with the hooks 26 and 26 and one complete movement of the crank 25 in one direction,

it being understood, of course, that the candy gaged the candy below the hook 26 and above This is substantially a reverthe hook 26.

sal of the position of the parts shown in Fig. 6. Fig. 12 shows a further movement of the parts and brings the hooks to substantially the positions shown in Fig. 3. From the foregoing it will be seen that the hooks 26 and 26 pass in and out and about the hook l9 and subject the candy to a continuous pulling action, the action of the books 26 and 26 being to pull the candy against the hold of the hook l9 and also to wind up the pulled candy.

Having thus explained the nature of my invention and described a way of making and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim, and desire to secure by Letters Patent, is

In combination with the cooperative elements of a candy-pulling machine, a stationary puller or hook, a plurality of rotating hooks, and means for vibrating the latter across the plane of the former.

In testimony whereof I have aflixed my signature in presence of two witnesses.

CHARLES THIBODEAU.
